摘要

我们利用超连续产生和非线性参量变换的方法开发了一种激光系统，它能形成持续时间为数次场振荡、中心波长为 910 nm 的飞秒脉冲，并与泵浦激光器的种子辐射同步。飞秒脉冲的持续时间为 20 fs，重复频率为 1 kHz，脉冲能量高于 5 μJ。为了进一步放大到高于 40 mJ 的能量，还开发了一种泵浦激光器，并计算了参量放大器的主要参数。所开发的激光系统将用作 PEARL petawatt 参数激光系统的起始部分。

Formation and Parametric Amplification of Femtosecond Pulses with a Central Wavelength of 910nm Using Radiation from a Subpicosecond Ytterbium Laser

We use the methods of supercontinuum generation and nonlinear parametric transformations to develop a laser system that forms femtosecond pulses with a duration of several field oscillations and a central wavelength of 910 nm, which are synchronized with the seed radiation of the pump laser. The duration of femtosecond pulses was 20 fs at a repetition rate of 1 kHz and a pulse energy higher than 5 μJ. For further amplification to an energy higher than 40 mJ, a pump laser has been developed, and the main parameters of the parametric amplifier have been calculated. The developed laser system will be used as the starting part of the PEARL petawatt parametric laser system.
